Name: The Stone Operation.
Artist: Hieronymus Bosch
Location: Museo del Prado, Madrid, Spain
This painting is also called 'The Cure of Folly (Extraction of the Stone of Madness)'
There was an old Dutch saying for a person of odd behavior that he had 'a stone in the head'. Trading on credulity of simple people, charlatans would offer to extract stones. They always found patients among those with headaches. The 'surgeon' would then tie his patient safely to a bench, make a small cut and under cries, moans and groans of the victim produce a pebble or two covered with blood. In this painting Bosch has painted a flower as the object being removed. The flower is a tulip which, in the Netherlands is a metaphor for being mad.
